Back firing issue


Recommended Posts

I'm not an expert, but mine was doing the same thing. The problem was more gas was pouring in then being burnt so it spits it out (Backfires). You could put a new float kit in it, it might fix the problem. I put the whole kit, and it fixed it. Depends on what you want to do, the float kit or the whole thing. Hope it helped!

Questionable advice above. Assuming the valves are in spec it sounds like a pilot circuit issue. Check/clean the pilot jet/passages are clear then look at the fuel screw setting. Hard to start cold and backfiring on decel are both symptoms of a LEAN pilot circuit. Id try opening the fuel screw 1/4 turn at a time and retesting. Also check the throttle slide isnt in upside down, as that will cause backfiring aswell.
